Comments: Several people are living in an underground bunker because of a nuclear war, caused by religious beliefs. They share the space with the Strangers and the Invisibles, who come in the form of a cold, green mist during the Cold Hour. All seem able to kill this small group of people.
This Spanish film is shot well. The main character is a young boy with a camcorder. The acting is good and the plot moves along well. It's terrifying at parts. There's a short scene after the credits that leaves the audience with a question.
